' HUMIDIFIERL Specification of Letters Patent.

v 9 Application filed Apri116, 1906. Serial No. 311,847.

To all whom it may concern.

Be it known that LIFRANK Bl comm of full, clear, and exact descri tionof the same, reference being had to t e accompanying drawings, formingpart'of this specification;

This invention has reference to improve ments in air moistening machinesor humidlfiers.

One object of the invention to so con struct a machine of this naturethat a large quantity of air may bedraw'nover a great area of surface towhich moisture is constantly supplied. v Q 7 Another object of. theinvention is to so construct a machine of this nature that the air afterpassing over the m'oistened areas may issue from the machine in a largeundi vided volume.

Other ob'ects of the invention will from the following description; v

The invention consists the peculiar cone struction of the casing. r

The invention also consists in the novel construction of the moisturecarrying dev1ces.

The invention also consistsin the casing having ends furnished withoutlet openings, and moisture carryingdevices having 0 one ingsregistering with said outlet openmgs, and means for drawing air intosaid casing at an angle to said outlets.

The invention also consists in such other novel features of constructionand combination of parts as-shall hereinafterbe'more fully described andpointed out in theyclaims. Figure 1, represents the machine in endelevation, the casing being shown in section. Fig. 2, represents avertical sectional view of the casing taken at right angles to-Fig. 1. 9Similar numbers of reference designate corresponding parts throughout.

As shown in thedrawings the casing has the bottom 5, the s'ides' G-fi,the ends '77 having the large outlet openings 88, and the top 9 havingthe inlet compartment 10 forming an open inlet channel for the supfplyof air to the casing. v This, channel 10. is urnished with the crossmembers 11 and '12 having bearingsin which the vertical shaft 13, havingthe fan 14 and the drive pulley 15,

is j ournaled;

Mounted on the member 12 is the casing tank is also appear 7 f suitablyspaced, the central openings 30 in s eed, the centrifugal fan in thecasing l raws water from t :pipe 17 and discharges this water under 16of any ordinary and well known form of centrifugal pump which isdesigned to be driven bythe shaft 13; to this casing is connectedthesupply pipe '17 and one or more deliverypipes, as 18, both of whichextend "into the tank 19 located at the lower portion of the casing,water being drawn upward from said tank through the ipe 17 by the actionof the pump and de ivered to. the

tank under pressure from said pump through the pipe 18. Water issupplied to said tank 19 by means of the pipe 20 the flow of water beingcontrolled by the float valve 21; said provided with the overflow e 22.Within the casing are mounted the end frames 23*23 each having a roller,or other anti friction, bearing 24 and on these bearings is rotatablymounted the shaft 25 having the spiders 26-26 the arms of the respec-:tive spiders being connected by the rods 27-27 on'which a great numberof their annular disks 2828 and 29 are mounted and these diskscorresponding approximately in dimensionsto the dimensions of the outletolpenings 8'-8 of the case.

One, or more, of

ese disks, as 29, is furnished with a series of blades, or buckets,31r31 adjacent to the path of which is located the nozzle of the pipe orpipes 18 whereby water issuing from said nozzle, or nozzles, may impingeagainst said blades and effect the rotation of the combined series ofannular disks 28,28 and 29'at a comparatively slow speed.

The water supplied to the tank 19 may, if

:desired, be at a temperature higher than that ofthe atmosphere, toeffect the more rapid evaporation of the water, and is preferably ofsuch a height in the tank that the lower portions of the disks 2828 and29 pass through the water as said disks are rotated. Vfhen the fan 14 isdriven, usually at a high 16 e tank 19 through the pressure through thepipe 18 against the blades or buckets 81 of the disk 29, thus effectingthe comparatively slow rotation of said disk 29, its shaft 25 and theother disks 2828 carried by the spiders on said shaft. As these disksrotate their wetted surfaces are. carried upward the moisture beingcarried in an opposite direction to the air entering through the fanchamber 10 and the air passing down between the constantly receivedWetted surfaces of the disks which form numerous fiat channels bothwalls of which supply moisture to the air passing therebetween, the airafter reaching the central openings of the disks being free to flowlaterally out through the openings 8-8.

It is of course evident that any well known means may be utilized toeffect the rotation of the humidifier disks without departing from thespirit of this invention as, however, it is preferable that said disksshould be driven at a slower speed than the fan 14 some simple method,such as that shown, should be used in order to avoid the use ofcomplicated and expensive drive gear.

Having thus described my invention, I claim as new and desire to secureby Letters Patent.

A humidifier comprising a casing having air outlets in their ends, atank in said casing,

a humidifier element rotatably mounted in said casing and comprising aseries of disks one of which is furnished with blades, a pump, pipescommunicating with the pump casing and with the tank one of said pipesbeing adapted to direct water passing from the pump under pressureagainst the blades of said disk to drive the humidifier element, as andfor the purpose described.

In testimony whereof I aflix my signature in presence of two witnesses.
